Q: What are titanium screws used for?
A: Titanium screws are excellent for many applications. They are often used for their excellent resistance to saltwater and chlorides. Titanium screws can service many decades in even polluted seawater and are resistant to both stagnant and rapidly moving oceans. Titanium is also almost inert to chlorides making it ideal for chlor alkali.
Titanium screws are known for their unmatched strength to weight ratio. They are many times stronger than 316 stainless, at half the weight. Grade 5 is 4 times stronger and Grade 2 is 2 times stronger.
Also, titanium screws are bio-compatible, so they find a place in many medical applications.
